Since Rollins had not yet officially signed his contract, Giants general manager Bobby Evans declined to comment on the move.
An Oakland native who graduated from Alameda's Encinal High School, Rollins is primarily known for his 15-year tenure with the Philadelphia Phillies, which began in 2000. He captured the National League's Most Valuable Player Award in 2007 besides winning four Gold Glove Awards for defensive excellence and making three NL All-Star teams.
